application tiled n'ne 27, 1923. Serial No. 647,980,

To (UZ whom it may concern:

Be it known that I, JAMES A. CRUMLEY, a citizen ot the United States, residing at Charleston, in the county of Kanawha and State of West Virginia, have invented certain new and useful improvements in Pumping Rigs, of which the following is a specification.

This invention relates to improvements in" f nation and arrangement of parts hereinafter more 'fully described. shown in the accompanying drawings 'and claimed.

ln the drawings, wherein like reference characters indicate corresponding parts ti'iroughout the several views7 Figure 1 is a side elevational View of a rig foundation constructed in accordance with the present invention,

Figure 2 is an enlarged sectional 'view' through the walking beam and taken substanlially on line 2 2 of Figure i.

Figure 3 is an end view of the walking beam,

Figure 4 is a view of one of the crank shaft. supporting posts and adjacent parts, and

Figure 5 is au enlarged elevational view ol` the hitman,

Referring more iu etail lo the several views. the invciuion enibmlies a vertical sur porting' post which is prefer-abi)v in the nature of apiece of pine with its lower cnd threaded in a base plate-ti which is suitabl)v fianged and to a concrete Y bolted as at i foundation 8. A saddle box 9 is threaded on to the upper end of the post 5 and embodies upper horizontally aligned split clamps 10 in which the ends orf a shaft 1l are clamped, the clamps l0 being spaced apart to receive the saddle l2 of a walking beam i3 therebetween, which saddle embodies a lower portion in which the shaft li is'freely movable for permitting free rocking of the walku ing beam, and inverted @shaped clamps or bolts la which secure the saddle to the centrai portion of the walking beam. The walking beam 13 preferably consists 0i a length ot pipe with upwardly directed end portions connected by a brace l5 which also consists in a smaller pipe section with its ends suitablyv secured as atv i6 to the ends of the walking beam i3 as shown in Figurey 1.

Directly beneath one end of the Walking beam 13 there is providedl a pairof short posts 17 which are preferably formed from ends threaded into a base plate 18 suitably bolted as at 19 to aconcrete foundation 20. Suitable bearing caps 2i, ot split form, are threaded on the upper ends ot the post 17, and the usnalcranl; shaft 22 ot the band,

wheel 23 is journaled in these bearings 2l..l lt is to be understood that the band Wheel Q3 is disposed between the pair of posts i?,

suitably 'fastened as atsito the sill 26 o the derricli. The posts il' are braced in the opposite direction by means of bumping poles Il' which are bolted to the posts l? and are adapted to extend from the engine 'foundation. not shown. The, bracesvit and 27 are preferably constructed of smali pipe having their ends flattened so that they may be convenientl)v bolted to the posts i7 and siii QG, and tirs is also true with respect to a further bruce 2 8 provided between the upper end portion of the walkingr beamsupporting post 5 and the base 18 ot 'one of the posts 1T. Each end of the walking'A beam 123 is preferably longitudinally slotted as indicated at 28 in Figure 3, providing a pair oi leg por- To sections of pipe and which have their lower tions each, of which carry one of a pair of stirrup boxes 29 having split bearings for reception of the U-shaped stirrup 30 of a pitmanl, the pitman 3l having its central portion preferably in the form of a section of pipe withthe stirrup 30 secured on one end thereof by bolting or the like as at 32, and having a suitable `journal box 33 fa. ltened on the other end thereof for reception of the crank portion of the shaft 22 or the like. lt will be seen from the foregoing description that the various elements of the construction are, as a whole, mainly con structed as pipe'sections with readily attachable parts so that a foundation of this kind may be readily assembled at a cheap cost and in a small amount of time. Also, the device that is produced is eiiicent in operation and embodies strength and durability so that prolonged service is insured.

Minor changes may be made without departing from the spirit and scope of the m Vention as claimed.

What I claim as new is:

l. In a pumping` rig for oil wells, the combination with the horizontal sill at the lower portion of a derrick, of a anged base fixed at one side of and below said sill, a

post mount/ed in said base, a saddle box xed upon the upper end of said post and including spaced clamps having a shaft fixed therein and extending therebetween, a saddle liournaled upon said shaft, a walking beam, U-shaped bolts engaging the walking beam and the saddle for clamping the latter together, a pair of spaced relatively short posts mounted adjacent 4the iirst named post, in spaced relation, and having bearingcaps on the upper end thereof, a crank shaft rotatable in said bearing caps, a pitmancon nected to the crank of said shaft and having a stirrup thereon, and a pair of cooperating stirrup boxes upon the end o-f the walking beam above the second named posts for reception of the stirrup of said pitman adapted to connect the crank shaft with the walk ing beam,

2; ln a pumping rip,F for oil wells, the combination with the horizontal sill at the lower portion of a derrick, of a flanged base iixed at one side of and below said sill, a post mounted in said base, a saddle box fixed upon the upper end of said post and includl ing spaced clamps having a shaft fixed therein and extending therebetween, a saddle journalled upon said shaft, a Walking beam, U-shaped bolts engaging the walking beam and the saddle for clamping the latter together, a pair of spaced relatively short posts mounted adjacent the rst named post 'in spaced relation,- and having bearing caps on the upper end thereof, a ora-.nk shaft on a band wheel mounted in said bearing caps,

. a pitman connected at an end to the crank of waiking beam above the eredita .l

. esos 'vie of cooperatingl stirrup boxes upon the end of the walking beam above the second named posts for the reception of the stirrup of said pitinan adapted to connect the'crank shaft with the walking beam, said post embodying a pipe section threaded into the flanged base and on the upper end of which is threaded the saddle boxes and said walkingl beam having the bearing 'cap secured in the central portion thereof, for cooperation with the saddle boxes in mounting said beam.

3. in a pumping rig' for. oil wells, the combination with the horizontal sill at the lower portion of the derrick, of a fiang .d base i'ixed at one side of and below sai sill, a post mounted in saidvbase,"a saddle box ixed upon the upper end of said post and including spaced clamps having a shaft fixed therein and extending therebetween, a. saddle journaled upon said shaft, a walking beam, ti-shaped bolts engaging the walking beam and the saddle for clamping the latter together, a pair of spaced relatively short posts mounted adjacent the iirst named post in spaced relation and having bearing caps on the upper end thereof, a crank shaft on a band wheel rotatably mounted in the bearing caps between the last named posts, a pitman connected with the crank of said shaft and having a stirrup, and a pair of cooperating stirrup boxes upon the end of the Walking beam above the second named post for reception of the stirrup of the pitman adapted to connect the crank shaft with the Walking beam, -a tubular inclined brace between the base vof one of the second named posts and the top of the i'irst named post, a second inclined brace between the bottom sill of the derrick and each-of said second named posts, and oppositely extending bumping poles attachedvto the second named posts.

el. ln a pumping rig for oil wells, the combination with the horizontal sill at the lower portion of a der-rick, of a flanged base fixed at, one side of and below said sill, a post mounted in said base, a saddle box fixed upon the upper end of said post -and including spaced clamps having a shaftl fixed therein and extending therebetween, a saddie journaled upon said shaft, a walking beam, Ushaped bolts engaging the walking beam and the saddle for clamping the latter together, a pair of spaced relatively short posts mounted adjacent the first named post in.spaced' relation and having bearing caps upon the upper end thereof, a crank shaft on a band wheel rotatably mounted in the bearing caps between the last named posts, a pitman connected to the crank of said shaft having a stirrup on one end, and a pair of cooperating stirrup boxes on the end of the "d `nests,

for lecepton of the stirrup of 'the pitman adanted to connect the crank shaft with the Wal ing beam, a tubulaiinclined brace between the base of one of the second named posts and the 'top of the i'st named post, a second inclined brace between the bottom sill of the derrick and each of said second named posts, and oppositely extending bumping poles attached Vto the second named posis, said bumping poles and braces comprising 10 sections of pipe with flattened ends moulded to the members to which they attach.
